You could try applying a droplet of water to the edge of the pre-bonded
pieces.
Capillary forces should draw some water in between the plates and stick
the two together. It takes a little practice to get it right but I have
used this technique successfully in the past.
However, you may have problems with your electrodes when thermally
bonding glass at high temperature (with or without the presence of water).
